The SF6 filling and testing units facilitate the safe and efficient filling, topping-up and checking of system pressure in SF6 gas chambers. The operating points for SF6 monitoring can also be checked. All the equipment items are stowed in a handy carrying case.


Key Features

  • Safe filling and topping up with SF6
  • Easy checking of system pressure and operating points
  • Various connectors and adapters available



The units consist of the following principal components:

  • Connecting hose with connectors (depending on intended use)
  • Pressure reducing valve
  • Precision pressure gauge
  • Adapter
  • Safety valve
  • Needle valve for fine adjustments
  • Caps
  • Coupling (optional)

The individual components vary according to the intended use (filling, topping up or inspection). Appropriate adapters and connectors are available for every application.
